Edit - My conclusion for now is that the Aquarium Coop fertilizers are great if you want to keep it simple. The Easy Green is more concentrated than some of the other name brand products and I've read many of the great reviews indicating that it works well. Dry fertilizers may be the way to go if you want to save the most money, but requires more work than the Easy Green. Thanks to the suggestions for dry fertilizers. I think I'm going that route for now and will see how it goes. Hello, I know there are no specific easy answers as there are variables with different water, plants, etc. but I would like to see if I can switch over to using the Aquarium Coop fertilizers. I like to support local businesses, and could even save some money at the same time. I have been using Seachem products and did pick up some Easy Green last year. I'm wondering what some of the differences are. I also use the Seachem Potassium and noticed that Easy Green has more Potassium, but is it enough, or should I be adding more? Easy Green vs Flourish - It looks like the Easy Green has higher concentrations for the most part, but is also missing a few things and has less Iron. Does anyone know the reasons why? Should I be adding extra Iron with Easy Iron if I plan on using something like Excel or Easy Carbon? Maybe there's a video explaining this? Easy Carbon vs Excel I can't see what the active ingredients are from the pictures on the Aquarium Coop website (the product picture zoom doesn't actually zoom in on a more detailed picture), but I'm wondering what the differences are. One difference seems to be the gallons treated. Excel would treat somewhere between 3000-6000 gallons and Easy Carbon around 5000 gallons. Are the active chemicals the same? Is one safer to use (less toxic) or more beneficial for the plants? Easy Iron vs. Seachem Iron - These seem to be the same, except for Seachem being cheaper, although you can buy a larger size from Aquarium Coop to save money. Thanks!
